Bug Description

Upstream dropped the preliminary_hw_support flag for Skylake from code that'll land in 4.3. We will cherry-pick the most crucial bits before doing the same on 4.2-based Wily kernel. So this bug depends on the patchset for this bug:

https://bugs.launchpad.net/ubuntu/wily/+source/linux/+bug/1484486

there will be others to follow in order to remain in sync with vivid, but those are less important for the initial enablement.
